If you get the die to sit JUST RIGHT, that proportion may change, Hornady consistently sizes to .310-.311... I never had a case larger then .311 and all pass the gauge test.

You might want to call LEE and talk to them about it. At least get a new die set from them that properly sizes and also give them a heads up.

I have had the exact same issues with my Leee dies. They will not pass my EA go/no go, not even close. I have issues with not cycling consistently. I contacted Peter at Lee, and explained the situation. I sent 2 fired rounds, 2 fired then resized by my Lee dies, and 2 resized by my Hornady dies to him The rounds sized by Hornady are perfect every time and fit go/no gauge with absolutely no issues. I got the dies back from Lee, they said there was nothing wrong with the dies. They did not even take the dies sized by my Hornady out of the package. I am debating on sending them back again or throwing them in the scrap metal pile. Very disappointed in Lee at this point. Any suggestions?

I too had the problem with the Lee dies, the resized case would not fit in the EA go no go gauge without forcing it in, however it would cycle through the weapon. I checked the size of the case and found the same problem with the middle of the case. I purchased an RCBS die set and it solved the problem the resized case will fit beautiful in the EA gauge.

Just put my very first case through my RCBS die; 0.3112 right behind the shoulder. I'm using the RCBS lube pad because it's all I have right now... Waiting for my order of Hornady One Shot case lube to come in. It looks like I lost about a little less than a square quarter inch of laquer on one side of the case near the base. And the shoulder is looking just like factory.

You can add my name to the list of people that use the RCBS full length dies (purchased in August 2012) to the list that functions 100%. Have been through over 2000 reloads, and have never had a FTE or FTF. I do have to pay particular attention when setting up the bullet seating die to make sure the die body is set low enough to get rid of the lip expansion caused during the resizing process, but not low enough that it creates a crimp. The reloads were feeding just fine in the FsN, but after about 1000 rounds I finally purchased the EA go/no go gauge, and discovered the lip of the case was not to spec once the bullet was seated. A slight (less than 1/8 of a turn) adjustment on the seating die solved the issue.

I've done several hundred 5.7s with my Lee dies. Only one failure and that was the first set up round .......I pushed the shoulder down too far and got the dreaded shoulder hump Everything else has ran like a champ

GONRA has said this a zillion tymes - but my RCBS Small Base 5.7x28FN dies verked perfectly right out of the box.
Used in heavy duty Hollywood Senior press, STP Oil Treatment case lube, RCBS shell holder.
Sized right back to factory specs (miked along side a FN factory round)
coating didn't come off (OK - one time in 970 cases) and Shoot Great!.
